CVE-2026-30849

Estado: AnalizadaCrítica (9.3)—

Mantis Bug Tracker (MantisBT) is an open source issue tracker. Versions prior to 2.28.1 running on MySQL family databases are affected by an authentication bypass vulnerability in the SOAP API, as a result of an improper type checking on the password parameter. Other database backends are not affected, as they do not perform implicit type conversion from string to integer. Using a crafted SOAP envelope, an attacker knowing the victim's username is able to login to the SOAP API with their account without knowledge of the actual password, and execute any API function they have access to.

Version 2.28.1 contains a patch. Disabling the SOAP API significantly reduces the risk, but still allows the attacker to retrieve user account information including email address and real name.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Explotación remota de API SOAP sin autenticación (AV:N, PR:N, UI:N). Impactos: acceso a cuenta válida (T1078.002), enumeración de cuentas (T1087.001) y acceso a PII (email, nombre real, T1552.007).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

Las versiones anteriores a la 2.28.1 que se ejecutan en bases de datos de la familia MySQL están afectadas por una vulnerabilidad de omisión de autenticación en la API SOAP, como resultado de una comprobación de tipo incorrecta en el parámetro de contraseña. Otros backends de base de datos no están afectados, ya que no realizan conversión de tipo implícita de cadena a entero. Usando un sobre SOAP manipulado, un atacante que conoce el nombre de usuario de la víctima puede iniciar sesión en la API SOAP con su cuenta sin conocimiento de la contraseña real, y ejecutar cualquier función de la API a la que tenga acceso. La versión 2.28.1 contiene un parche. Deshabilitar la API SOAP reduce significativamente el riesgo, pero aún permite al atacante recuperar información de la cuenta de usuario, incluyendo la dirección de correo electrónico y el nombre real."
